Balcony Power Plant Austria 2026: 800W Allowed — Rules, Registration & €150 Grant
Summary (TL;DR)
TL;DR: Balcony power plants up to 800W feed-in power are allowed in Austria and only need to be reported to the grid operator (no permit needed). Since September 2024, renters no longer need consent from all owners - a public notice suffices. Costs: €400-800 for a complete set. Savings: €100-200 per year. Federal subsidy doesn't apply, but some states and municipalities subsidize balcony power plants.
What is a Balcony Power Plant?
A balcony power plant (also mini-PV or plug-in solar system) is a small photovoltaic system that you can install yourself and simply plug into an outlet. The generated electricity is used directly in the household and reduces your grid purchase.
Legal Situation in Austria 2026
| Criterion | Regulation |
|---|---|
| Maximum feed-in power | 800 watts (inverter) |
| Module power | Unlimited (only inverter counts) |
| Permit | Not required |
| Registration | Inform grid operator (2 weeks before) |
| Plug | Schuko or Wieland allowed |
| Meter | Must have reverse current blocking |
New Rental Law Since September 2024
Good news for renters: Since September 1, 2024, you no longer need consent from all apartment owners. A public notice suffices - if no justified objection is filed within 2 months, you may install the balcony power plant.
Installation Step by Step
- 1. Check location: Balcony, terrace, facade, or garden with south orientation
- 2. Buy balcony power plant (complete set recommended)
- 3. Inform grid operator (online form, 2 weeks before commissioning)
- 4. For rental apartment: Post notice, wait 2 months
- 5. Mount modules (balcony railing, stand, wall mount)
- 6. Plug in and produce electricity
Costs and Savings
| Item | Amount |
|---|---|
| Balcony power plant 800W (complete set) | €400-800 |
| Optional bracket | €50-150 |
| Annual yield (Austria, south balcony) | 600-900 kWh |
| Savings at 22 ct/kWh | €130-200/year |
| Payback | 2-4 years |
Subsidy for Balcony Power Plants
The federal subsidy (EAG investment grant) does NOT apply to balcony power plants - a separate feed-in metering point would be required. But: Some states and municipalities offer their own subsidies.
- Check your municipality's website
- Ask the state energy provider
- Some grid operators have subsidy programs
What Happens to Surplus Electricity?
With a balcony power plant, surplus electricity flows into the grid for free - you don't get compensation. The meter must not run backwards (must have reverse current blocking). Therefore: Consume as much as possible yourself, e.g., run devices during the day.
Tips for Maximum Self-Consumption
- Run washing machine, dishwasher during the day
- Refrigerator/freezer benefit automatically
- Charge e-bike during the day
- Optional: Small storage (from €200) for evening hours
- Use smart plugs with timer
Frequently Asked Questions About Balcony Power Plants
Can I connect the balcony power plant myself?
Yes. For Schuko plug connection, no electrician is needed. Some experts still recommend a Wieland plug with professional installation - but this isn't mandatory.
What happens during power outage?
The balcony power plant automatically shuts off (NA protection). It cannot serve as backup power.
Can I operate multiple balcony power plants?
Yes, but total feed-in power must not exceed 800W. With multiple systems at the same metering point, you must coordinate this.
Do I need a new electricity meter?
Your meter must have reverse current blocking. Modern digital meters and smart meters already have this. With old Ferraris meters, the grid operator may need to replace (free of charge).
Conclusion: The Easiest Entry into Solar Energy
A balcony power plant is the most uncomplicated way to generate your own solar power. No permit, no craftsmen, payback in 2-4 years. The path has been clear for renters since 2024 too. With €400-800 investment and €150 annual savings, it's a no-brainer for anyone with a south-facing balcony.
